Abstract:Carboxyethylated fibers were ground or homogenized under high pressure to obtain microfibrillated cellulose (MFC). Then the MFC-filler composite with high filler content (70%) was prepared using the mixed slurry of MFC and GCC by coating process. The differences in mechanical properties, optical properties and surface properties of the composite materials prepared using MFC with different sizes which were characterized through laser particle size analyzer were investigated in this paper. It was found that MFC3, which was fully fibrillation by the co-action of ground and high pressure homogenizing，but still contained proper amount of long fibrils, could obtain composites with better comprehensive performance. When the grammage was 110 g/m2, the tensile index of the composite was 20.4 N·m/g, the burst index was 0.77 kPa·m2/g, the opacity was 97.2%, and the smoothness reached to 1565 s.
